Application filed August 13, 1926f Serial No. 128,953..

My invention relates to connections for I- beams and columns, and particularly to devices of this nature adapted to secure sup' .15 forms in which the principle of the invention may be illustrated.

In said annexed drawing:

Figure 1 is a fragmentary elevation showing a beam connected to columns by means of the improved connecting means herein described and claimed;

Figure 2 is a side elevation of the improved connecting means shown in Figure 1,the view being upon an enlarged scale;

Figure 3 is a front elevation of the improved connecting means shown in Figure 2;

Figure 4: is a view similar to Figure 2, showing a modified form of connecting means;

Figure 5 is a front view of that form of connecting means shown in Figure 4;

Figure 6 is a view similar to Figure 2,

showing a second modified form of connecting means; and Figure 7 is a front View of that form of connecting means shown in Figure 6.

Referring to the annexed drawing which the same parts are indicated by the same respective ordinals in the several views, I denote in Figure 1 a pair of columns by the ordinals 1, to which is secured a transverse beam 2 by means of one form of my improved connection. This improved connection is a rocker bearing seat which permits the beam to be deflected under load without subjecting the bearing to turning stress. The details of this connection comprise a casting 4 secured by means of the bolts 5 to a face 3 of the column 1, and a bearing plate 6, Figures 1, 2 and 3, secured to the bottom flange of the beam 2 by bolts 7. The bearin plate 6 it formed with a pair of depen ing ears 8 which provide bearings for a transverse pin 9, which also 55 intersects side plates 10 and the central rib 11 of thelower casting 4 and is retained by means of cotter pins 12. j j l It will be apparent from the description of the elements shown in Figures 1, 2 and 3 that, when the beam 2 is deflected under load, as shown by the dotted line in Figure 1, the ends of the beam 2 and bearing plates 6 will turn upon the pins 9 and permit the deflection of the beam 2 without subjecting the support or connection to any turnin stress. I

In the modification shown in Figures ,4 and 5, the pin 16 serves merely to hold the castings together,,and the bearing plate 18 is formed with a smooth finished surface 18 adapted to roll upon corresponding surfaces 15 formed upon the spaced parallel ribs 15 of the lower casting 14. The connecting pin 16 intersects the depending ear 18 formed upon the bearing plate 18 as well as intersecting the ribs 15, and is held by the cotter pins 12. 7

Referring to the modification shown in Figur'esG and 7, the lower casting is denoted by the ordinal 19 and is formed with spaced parallel ribs 20 intersected by a transverse connecting pin 21 which also intersects a depending ear 23 formed upon the bearing plate 22, and is held in position by the cotter pins 12.

Inall three forms of devices shown and described, I direct attention to the clearance space 24cbetween the bolts 5, permitting the insertion and operation of a standard socket wrench;

The multiple-part support provided by the constructions shown and described furnishes a hearing which will adjust itself to the defiected beam and eliminates the enormous turning stresses introduced into unitary anchors or supports ordinarily used for this purpose.

What I claim is:

1. Connections for columns and beams comprising, in combination with a supporttively, bearings formed in one casting within which the other casting can turn, and means for holding the castings together.

3. A connection for a column and a beam comprising a casting adapted to be secured to a side face of a supporting column and formed with vertical plates, a second casting adapted to be secured to the bottom face of a transverse beam and formed with depending ears, and a pin intersecting said plates and ears for securing together said castings and upon which said beam casting can turn.

4. A connection for a column and a beam comprising a casting adapted to be secured to a side face of a supporting column and formed with vertical side plates and a vertical intermediate rib, a second casting adapted to be secured to the bottom face of a transverse beam and formed with depending ears adapted to register between said plates respectively and said rib, and a pin intersecting said rib and plates and ears for securing together said castings and upon which said beam casting can turn.

Signed by me this 19 day of July, 1926.
